To all whom it may concern:

Be it known that I, JESSE P. ROBERT, a citizen of the United States,residing` at Pittsburg, in the county of Allegheny and State ofPennsylvania,have invented certain new and useful Improvements inDisinfeoting` Apparat us; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it. pertains to make and use thesame, reference being had to the accompanying drawings, which form apart of this specification.

My invention relates to an improved disinfecting apparatus; and itconsists in the certain details of construction hereinafter specified.

In the accompanying drawings, Figure l is a central sectional elevationof 4my improved apparatus as constructed in accordance with myinvention. Fig. 2 is a plan view of the same, a part of which is shownin section.

To put my invention into practice, I provide a cylindric metallic vessela, having a closed base and a perforated concave top h, through which aliquid disinfectant may escape. Centrally located Within this vessel ais a coneshaped chamber c, which forms an-annular space within thevessela. The space between vessel c and the outer Wall is filled withasbestus, mineral Wool, orother like indestructible and porous materiald. This annular space and the interior of the chamber c are incommunication with each other by means of ports or openings e, formedthrough the base of the partition. This cone-shaped chamber c isprovided with\an opening at the top and fitted with a screw-cap f torender the same air-tight. At the back of the apparatus is secured adisk g, having screw-holes formed therein for the purpose of attaching.the apparatus to the wall of a room.l A'small ring h, att-ached to thescrew-cap f, serves as a means for suspending the same to a hook ornail. Surrounding the perforated top of the apparatus is an annular rimt', which will pre- Vent the fluid from the apparatus from ru nning downthe outside.

In operation the cap f is removed and a liquid disinfectant placed inthe inner chamber c and the cap f replaced, which renders the apparatusready for use. The liquid gradually Saturates the fibrous material, andthe vapors arising escape into the room.

Having thus described my invention, I claim- The herein-described devicefor vaporizing disinfectants, consisting of the vessel c, havingcentrally located therein a chamber c, provided with the openings e,leading from said chamber c into the vessel a, the fibrous iilling d,the perforated top h, screw-cap f, and suitable means for att-aching'thedevice to the wall of a room.

In testimony that I claim the foregoing I hereunto affix my signaturethis 11th day of October, A. D. 1890.
